Hi, hope ime on the right forum, my 2007, auto creeps forward in drive but sometimes dont respond to the gas pedal, if I put it in manual and back again will respond, I have a i-soft diagnostic tool which brings up No faults, help please, am a newbie to Landys about 4weeks.

Problem I have is, when in drive sometimes, creeps forward but nothing on the gas pedal, any ideas, diagnostics not showing anything, move it into manual then back to drive sometimes works, help please.
